Abstract
Product made from flat material. A first strip has portions(s) at an angle to reference plane; a second strip is spaced from the first and parallel to it and has portion(s) with angle to reference plane opposed to that of first strip's portion. A strap joining the two portions has first second end portion at angle of first second portion and central portion twisted about long axis of strap. Preferably, strips are separated along their whole length by distance equal to strap length. Procedure: >=2 long, aligned openings are made in flat material, to delineate bands at either sides of the openings, and strap is produced to connect the strips between the openings; at least one strip is bent from the plane of the material so that the strap is twisted about its long axis. Advantage: material with strength/weight ratio characteristic of honeycomb construction, but formable into curves without loss of strength. Application: e.g. aerospace.
